Why krypton and noble gas are not used in airships using the periodic table?
WITCHER [35]

Answer:

Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.

How many grams of water are produced when 35.8 grams of Calcium hydroxide reacts with lots of Hydrochloric acid?
Veseljchak [2.6K]

Are produced 72 grams of water in this reaction.

<h3>Mole calculation</h3>

To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

                          Ca(OH)_2 + 2HCl = > 2H_2O + CaCl_2

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:2, so we can perform the following expression:

MM_{Ca(OH)_2} = 74.1g/mol

                                           MM = \frac{g}{mol}

                                             74.1 = \frac{35.8}{mol}\\mol = 2

So, if there are 2 mols of Ca(OH)2:

                                  Ca(OH)2    |    H2O

                                          \frac{1mol}{2mol} =\frac{2mol}{xmol}

                                             x = 4mol

Finally, just find the number of grams of water using your molar mass:

MM_{H_2O} = 18g/mol

                                              18= \frac{m}{4}\\m = 72g

So, 72 grams are produced of water in this reaction.
